arm64: dts: qcom: Add lemans evaluation kit (EVK) initial board support

Lemans EVK is an IoT board without safety monitoring feature of
Safety Island(SAIL) subsystem.

Lemans EVK is single board supporting these peripherals:
  - Storage: 2 × 128 GB UFS, micro-SD card, EEPROMs for MACs,
    eMMC on mezzanine card
  - Audio/Video, Camera & Display ports
  - Connectivity: RJ45 2.5GbE, WLAN/Bluetooth, CAN/CAN-FD
  - Sensors: IMU
  - PCIe ports
  - USB & UART ports

On top of lemans EVK board additional mezzanine boards can be stacked
in future.

Implement basic features like uart/ufs to enable 'boot to shell'.
